Why It Matters

As the demand for green hydrogen grows, understanding the cost drivers in its production technology is crucial. This research highlights how advanced manufacturing techniques can unlock economies of scale, directly impacting the commercial feasibility of PEM electrolyzers and their role in a sustainable energy future.

Key Finding

By adopting high-throughput, automated manufacturing processes, the cost of PEM electrolyzer systems can be more than halved, dropping from $515/kW to $230/kW as production scales from 10 to 10,000 units per year.

Key Findings

• PEM electrolyzer stack costs can be reduced to $323/kW at a production volume of 10 MW/year.
• Stack costs can further decrease to $165/kW at a production volume of 10,000 systems/year.
• Uninstalled system costs can drop from $515/kW at 10 units/year to $230/kW at 10,000 units/year.
• Balance of plant costs show less significant reduction due to reliance on outsourced components.
